MBTA Announcement: Worcester-Framingham Commuter Rail Line Track Work

I noticed that the MBTA finally posted something to their website regarding the Worcester-Framingham line track work beginning on Sunday.

Here is the T's "official" announcement about the track work:

Massachusetts Bay Commuter Railroad Company (MBCR), provider of commuter rail service to the Massachusetts Bay Transportation Authority, would like customers to be aware that CSX, which owns the railroad right-of-way and is responsible for track maintenance on the Worcester/Framingham Commuter Rail Line, will replace rails beginning on Sunday, March 9th with work expected to conclude at the end of Monday, March 17th.

At the request of the MBTA and MBCR, CSX has staggered the project schedule to minimize delays for commuter rail customers.

As a result of this project, certain off peak MBTA commuter rail trains (outbound and inbound) will experience delays of up to at least 30 minutes.

Passengers should also be aware that morning rush hour trains may experience up to 10 minute delays due to temporary speed restrictions that will be in place until the work is complete.

We apologize for any inconvenience you experience because of this project.

Work will take place as follows:

Phase 1

Duration:

Sunday, March 9th through Wednesday, March 12th.

Delays:

Sunday, March 9
Train #562, #564, #565, #566, and #567, can expect delays between 20 and 30 minutes.

Monday, March 10 through Wednesday, March 12

The following trains can expect delays of up to 30 minutes.

OUTBOUND: Train #533, #535, #537, and #539
INBOUND: Train #534, #536, #538, and #540

No work will be performed March 13th through 15th.

Phase 2

Duration:

Sunday, March 16th through Monday, March 17th.

Delays:
Sunday, March 16Train #552, #553, #556, and #557 will be bused between Grafton and Worcester.

Train#560 and #561 will not be bused but can expect delays between 20 and 30 minutes between Grafton and Worcester.

Monday, March 17
Train #509, #513, #518 and #524 will be bused between Grafton and Worcester.

Train#519 and #530 will not be bused but can expect delays between 20 and 30 minutes between Grafton and Worcester.

I don't understand the purpose of the MBCR's website. They link to the MBTA's site for most information (which is most curious since Dan Grabauskas claims the MBTA isn't responsible for the commuter rail lines) and they have schedule information going back to 2006 for some lines.

Does this mean the rest of the on-time performance for March 2008 won't matter because of the line work?

Does anyone know why on-time performance stats haven't been officially published?

Crazy!
